Intravascular ultrasound (IVUS) is a newly developed diagnostic modality for atherosclerosis. Early in vitro studies showed that IVUS could identify normal vessel structures and atherosclerotic lesions, such as intimal thickening, lipid-rich plaque, fibrous plaque, and calcification. In clinical settings, IVUS offers precise quantitative measurement of vascular stenosis as well as providing new information regarding the transmural distribution and the qualitative assessment of vascular atherosclerotic lesions. IVUS is also useful for assessing the results and the mechanisms of catheter-based interventional therapeutic devices, such as balloon angioplasty, laser angioplasty, stent, and atherectomy. The development of three-dimensional reconstruction of ultrasound images would enhance the diagnostic quality and afford a reliable guidance for interventional therapeutic procedures.
血管内超声（IVUS）是一种新开发的用于诊断动脉粥样硬化的方法。早期的体外研究表明，IVUS能够识别正常血管结构以及动脉粥样硬化病变，如内膜增厚、富含脂质的斑块、纤维斑块和钙化。在临床环境中，IVUS不仅能对血管狭窄进行精确的定量测量，还能提供有关血管壁内病变分布及血管动脉粥样硬化病变定性评估的新信息。IVUS对于评估基于导管的介入治疗器械（如球囊血管成形术、激光血管成形术、支架和斑块旋切术）的效果及机制也很有用。超声图像三维重建技术的发展将提高诊断质量，并为介入治疗程序提供可靠的指导。
